20.500.12556/RUL-164796 A high-efficiency programmable modulator for extreme ultraviolet light with nanometre feature size based on an electronic phase transition The absence of efficient light modulators for extreme ultraviolet (EUV) and X-ray photons considerably limits their real-life application, particularly when even slight complexity of the beam patterns is required. Here we report on a novel approach to reversible imprinting of a holographic mask in an electronic Wigner crystal material with a sub-90-nm feature size. The structure is imprinted on a sub-picosecond timescale using EUV laser pulses, and acts as a high-efficiency diffraction grating that deflects EUV or soft X-ray light. The imprinted nanostructure is stable after the removal of the exciting beams at low temperatures, but can be easily erased by a single heating beam. Modelling shows that the efficiency of the device can exceed 1%, approaching state-of-the-art etched gratings, but with the benefit of being programmable and tunable over a large range of wavelengths. The observed effect is based on the rapid change of lattice constant upon transition between metastable electronically ordered phases in a layered transition metal dichalcogenide. The proposed approach is potentially useful for creating tunable light modulators in the EUV and soft X-ray spectral ranges. light modulators extreme ultraviolet light ultrafast photonics condensed-matter physics true false true Angleški jezik Ni določen Članek v reviji 2024-11-12 13:44:27 2024-11-12 13:44:33 2024-11-22 14:56:10 0000-00-00 00:00:00 2024 0 0 Šestim oštevilčenim stranem članka (458–463) sledi še neoštevilčena stran.
